I am sure you won't be disappointed with the PAK. The format is great. It summarizes pretty well, synthesizes the main concepts and shows how they can be tested. It has 35 MOCK problems that are pretty good as well.

In addition to the PAK Study Manual, the following products are also ready:

The Flash Cards (Powerpoint slides highlighting the key important concepts)

The Test Aid (Originally designed 6 problems to simulate Exam time. Send back your answers and receive constructive feedback leading you to the exam.) and

The Exam Aid (Contains a list of 40 originally designed MOCK problems, different from the Test Aid problems and the problems in the Study Manual. This tool allows you to practice practice and practice. The level of difficulty of the problems are pretty similar to the one on the actual exam.)
